Hi FSL users,
My study uses DTI looking at 4 groups (3 patient and 1 control). I've run
TBSS, and even though I get significant voxels appearing the fstat image,
there are no significantly different (corrected) voxels for any contrast (I
tried them all!). The sample sizes of the groups aren't very large (and
slightly uneven) - perhaps this is part of the problem? Anyhow, I have
started looking at interhemispheric differences in FA within each group.
However, I am unsure as to how exactly I would go about comparing
asymmetries statistically between the groups using TBSS.
Could I run separate tbss_symm for each group and find R>L or L>R
differences? Although I would probably come across the problem of how to
compare between groups.
Anyone have any ideas/suggestions? Would greatly appreciate it.
